Satellite sphinx moth

The satellite sphinx is Eumorpha satellitia, a hawk moth in the family Sphingidae. Its common name refers to this species, not the unrelated noctuid moth also called the satellite. [Butterflies and Moths of North America](https://www.butterfliesandmoths.org/species/Eumorpha-satellitia)

Look for pale brown wings with a dark squarish mark near the middle of the forewing's inner margin. Adults have a wingspan around 4.5 to 5.25 inches, or 11.5 to 13.4 centimeters. [Butterflies and Moths of North America](https://www.butterfliesandmoths.org/species/Eumorpha-satellitia)

Its range runs from Brazil and northern Argentina through Central America, Mexico, and the West Indies to southern Texas and southern Arizona. That broad tropical and subtropical range explains why sightings in the United States are concentrated toward the southern edge of the country.

The documented host plant is treebine, Cissus, in the grape family Vitaceae. Adults also take nectar from flowers such as petunia, bouncing bet, and white campion, so caterpillar hosts and adult food plants are not the same thing.
